SEPARABLE BUTTON.

SPECIFICATION forming part of Letters Patent No. 391,076, dated October 16, 1888.

Application filed March 20, 1888. Serial No. 267,865. (No model.)

T0 @ZZ whom, may concern;

Beit known that I, EUGENE PRINGLE, a citizen ofthe United States, residing at Gloversville, in the countyofFulton and State of New York, have invented certain new and useful Improvements in Separable Buttons, of which the following is a specification.

My invention relates to separable buttons; and it consists of the parts, devices, and elements and combinations ofparts, devices, and elements hereinafter particularly described, and specifically set forth in the claims.

The objects of my improvements are toproduce a buttonhead which will have the studengaging part contained in the lower side half ofthe head,while the fastening-eyelet will form a part of the upper side half, so that the part of engagement of the coacting stud will be relatively below the lower half of the buttonhead, and also to provide in a stud an elastic holding-piece which will have engagement with the coacting button -head at a point relatively below the portion of the button-head above the material, while the body of the stud, instead of the elastic holding-piece, will itself sustain the pull, and, further, to provide specilic means by which my improvements can be carried into effect ina separable button. I attain these objects by the means illustrated in the accompanying drawings, forming apart of this specification, in which- Figure lis a sectional elevation ofa button head and stud, both secured to the material and embodying the improvements in this invention. Fig. 2 is asectional view ofthe buttonhead, showing a modified form of stud-holding piece. Fig. 3 is a sectional view of the fasteningeyelet piece. Fig. 4 is a view of the upper side clampingpiece, which contains the tube portion of the fasteniug-eyelet. Fig. 5is a sectional view of the lower side clampingpiece. Fig. 6 is a sectional view of the studengaging piece shown to be employed in the heads illustrated in Figs. 2 and 11 and adapted to be clinched on the lower side clamping-piece. Fig. 7 is a sectional view of the stud-engaging piece having the lower side clamping-piece clinched on it. Fig. 8 isasectional view of a stud-engaging piece, a lower side clampingpiece, and an eyelet turning piece secured together for use as shown in Fig. 1. Fig. 9 is a view of the saine pieces shown in Fig. 8, and showing a modified manner of securing the same together. Fig. 10 is a sectional view of the same pieces, showing the stud-engaging piece to have a modified form of engaging portion. Fig. 11 is a sectional view of a button-head having some of its parts modified in form of construction and relative arrangement. Fig. 12 is a sectional view of my improved stud for co-operation with the button-head. Fig. 13 is a plan View, from abovo,o'f the stud, illustrating the slitting of its base. Fig. 14. is a plan view of the same,

showing another form of slitting. Fig. 15 is a side elevation of the stud. Fig. 16 is a transverse side elevation of the same. Fig. 17 is a plan view of a piece which can be used to hold the spring catch in the slit. Fig. 1S isa sectional view of the same, and Fig. 19 is a sectional elevation of the stud embodying springcatchholding piece.

The same letters of reference refer to like parts throughout the several views.

In the drawings, A represents the upper side or top shell of the button-head. B is the upper side clamping-piece secured with said top shell, and O is the fastening-eyelet secured within the upper shell and having its tube portion c heldwithin the upper side clamping-piece.

I), Figs. 1, 2, 5, 7, S, 9, 10, and 1l, is the lower side clamping-piece, having a central perforation, d, and the upturned annular flange d.

E, Figs. 2, 6, 7, and 1l, is the studengaging piece, having the studieceiving opening e and the annular studengaging surface e', which is beveled inwardly and downwardly, as shown in Fig. 6, so as to hold with the engaging parts ofthe stud after its passage through said opening.

In Figs. 1, S, and 9 is shown piece E,which, with piece E2, forms the equivalent to piece E, the central perforations, e2 c, in said pieces forming the opening for the passage of the stud, as does perforation e in piece E, while the engaging rim e operates as does the engagingrim e in the said piece E.

In Figs. 1 and 8 the outer flange-rim, d2, of the under side clamping-piece, D, is shown to be clinched on the lower side of piece E', with piece E2 between, while in Figs. 9 and l0 the reverse is shown. In Fig. 10 the edge margin IOO of engaging-rim e4 is shown to be turned on itself, so as to produce a smooth rounded studengaging rim at the stud-receiving opening.

F, Figs. 1, 12, 13, 14,15, and 16, is the post of the stud S, and F is the base of the said post. This stud-post F and its base are shown to be slitted from the lower side of said base to a short distance below the -upper end of the post by one or more slits, f, as shown, and after being slitted the ring-form engaging piece G is placed within the upper-portion of the slit of the post F,when the portion of the post at the base -F will be contracted, so as to substantially close the slit f and form the hold- U inggroovef', as shown in Figs. 12, l5, and 16.

H, Figs. 1 and 12, is the stud-base-binding plate, provided with a central opening, h, through whichV the stud-post will readily pass, and I is a {ianged fastening-eyelenwhich is secured to the binding-plate H by clinching of theflange-rim h on4 the outer edge portion of theiiange i of the eyelet-,with the parts of the slittedrbase F between. said eyelet I forms the upper side clinchingpiece of the stud, while plate J forms the underside clamping -piece and is held secure with `the material and stud by the tube portion i' of the eyelet passing through the eentral perforation, j, of saidv plate .I and clinchi ing on the edge portion of the same.

In thisimproved separable button the ring- 'form engaging-piece G is made to be elastic, and it operates to hold with the engaging-rim e', or its described equivalent rim e4, to hold thebutton -head from accidentally partingfrom the stud, while the lateral direction of strain of the pull on the stud will cause the latter to r bejso drawn toward the sides vof the stud-receiving opening e, or its described equivalent e2 e3, 'as to cause the post to sustain the strain instead of the elastic ring-catching piece G, which is shown to be arranged lwithin the post in direction of its length, and so that this ringform-piece will receive the strain-on two points outside the stud.

By the above-described improvements I am enabled to cheaply produce a separable button which will be durable and strong in the 4fastenings of its parts to the material and in Vtheir connectionwith eachl other.

p' In Sonie cases, if preferred, the contraction of the base of the stud below the engagingpiece G (shown in Figs. 12, 15, and 16) can be omitted, and the said engaging-piece can be supported in place within the slit in the.

post bythe central boss, Z, made central with the 'disk Z of plate L. (Shown in Figs. 17, 18, and 19.) This can be readily effected by piacing the piece L against the slitted base of the stud-post, with the central boss, Z,within the central base of the same and against the lower r[his flange of thei side of the piece G, as shown in Fig. 19, and then securing this plate L with said base by any .suitable bindingpiece; or, if preferred, a strip, L', Figs. 2O and 21, having a central projection, ZZ, 'can be placed in the slit in the base F and lower portion of the stud-post to effect the same result.

Having described my invention, whatI claim, and desire to secure by Letters Patent, is

1. In a button-head of a separable button, the combination, with the eyelet-fastener iu the upper side portion of the button-head, of the stud-engaging piece E, having acentral stud receiving opening, e, or its described equivalent, and an annular stud-engaging rim, e', at the lower side of said opening, and the under side clamping-piece, D, secured to said stud-engaging piece and coacting with the said eyelet fastener, substantially as and for `the purposes set forth.

2. In a separable button, the stud formed by the combination of the slitted stud post F and the elastic ring-form engaging piece G, arranged in said post in direction ofits length for operation with an engagingpiece in the button-head, substantially as and for the purposes set forth.
